[0002] The industrial production of lithium iron phosphate, the cathode material for lithium-ion batteries, generates a large amount of process exhaust gas. This exhaust gas typically contains solid impurities such as raw material dust. Direct emission of these solid impurities not only results in product yield loss but also causes serious air pollution. Currently, the treatment of such dust-laden exhaust gas usually involves filtration using filters such as screens and bags to achieve preliminary purification.

[0003] However, during the filtration process, dust accumulates on the filter screen, causing it to become clogged. To ensure the continuous and stable operation of the treatment system, the filter screen needs to be cleaned or replaced. The filter screen is typically installed and secured with bolts. Each time the filter screen is replaced, operators must use specialized tools such as screwdrivers and wrenches to loosen, remove, and then tighten each screw individually, which is inconvenient.

[0023] This utility model provides an exhaust gas treatment device, solving the current technical problem of inconvenient installation and removal of filter screens. The exhaust gas treatment device includes an exhaust pipe 1, a filter screen 2, a locking block 3, and a push rod 4, wherein: The exhaust pipe 1 is connected to the exhaust gas source to deliver exhaust gas for treatment.

[0024] Reference Figures 1-4 The filter screen 2 is installed on one end of the exhaust pipe 1. The filter screen 2 is used to filter the exhaust gas to remove some solid impurities in the exhaust gas. The exhaust gas that has passed through the filter screen 2 can be transported again and further processed.

[0025] Reference Figures 1-4 The locking block 3 is installed on one side of the filter screen 2. The exhaust pipe 1 has an installation hole. When the locking block 3 is installed in the installation hole, the locking block 3 prevents the filter screen 2 from moving along the extension direction of the filter screen 2. The installation hole has a locking groove that matches the locking block 3. When the locking block 3 is engaged in the locking groove, the locking groove and the locking block 3 prevent the filter screen 2 from moving axially along the installation hole, thereby fixing the filter screen 2 on the exhaust pipe 1 so that the filter screen 2 can filter the gas passing through the exhaust pipe 1. When the locking block 3 is removed from the locking groove, the locking block 3 moves axially along the installation hole to the outside of the exhaust pipe 1, thereby removing the filter screen 2 for replacement or cleaning.

[0026] Reference Figures 1-4 Push rod 4 is slidably mounted on filter screen 2. One end of push rod 4 is mounted on locking block 3. Push rod 4 is used to push locking block 3 to move, thereby driving locking block 3 into the locking slot to fix filter screen 2, or driving locking block 3 to move out of the locking slot so as to remove filter screen 2 from exhaust pipe 1. The end of push rod 4 away from locking block 3 extends out of filter screen 2 so as to move locking block 3 by push rod 4. There are at least two locking blocks 3. The locking blocks 3 are evenly distributed around the filter screen 2. Push rod 4 corresponds to locking block 3 one by one, so that one push rod 4 drives one locking block 3 to move.

[0027] With the above structure, the exhaust gas treatment device provided by this utility model, when in use, removes impurities from the exhaust gas by installing the filter screen 2 on the exhaust pipe 1 after the exhaust gas passes through the filter screen 2. When installing the filter screen 2, first install the locking block 3 in the mounting hole, then move the push rod 4 to push the locking block 3 into the locking groove, thereby fixing the filter screen 2 to the exhaust pipe 1. When it is necessary to remove the filter screen 2, move the push rod 4 to push the locking block 3 out of the locking groove, and then move the locking block 3 out along the axial direction of the mounting hole. Therefore, this exhaust gas treatment device facilitates the installation or removal of the filter screen 2 from the exhaust pipe 1 by pushing the locking block 3 in and out of the locking groove via the push rod 4, making it convenient to use.

[0028] An optional implementation of this embodiment is as follows: Refer to... Figures 1-4 The locking block 3 includes a connecting rod 31 and a protrusion 32. The connecting rod 31 is slidably mounted on the filter screen 2, with one end extending away from the filter. The connecting rod 31 slides, thereby adjusting its length extending beyond the filter screen 2. The protrusion 32 is installed on the side of the connecting rod 31 away from the axial direction of the filter screen 2. That is, after the locking block 3 is installed in the mounting hole, it is located on the side of the connecting rod 31 closest to the wall of the mounting hole. A slot is provided on the wall of the mounting hole, allowing the locking block 3 to engage with the slot. The protrusion 32 and the connecting rod 31... The distance between the protrusions 32 and the filter screen 2 gradually decreases from the end of the protrusion 32 that is closer to the filter screen 2 to the end that is farther away from the filter screen 2. The protrusion 32 moves away from the wall of the mounting hole, so that the protrusion 32 gradually extends out of the slot. Therefore, the width of the end of the protrusion 32 that is farther away from the filter screen 2 is smaller, so that the protrusion 32 can enter and exit the slot. The push rod 4 is installed on the connecting rod 31. The push rod 4 moves, thereby driving the end of the connecting rod 31 with the protrusion 32 to move closer to or farther away from the slot, so as to fix the filter screen 2 to the exhaust pipe 1 or remove the filter screen 2 from the exhaust pipe 1.

[0029] An optional implementation of this embodiment is as follows: Refer to... Figures 1-4 The axial distance between the connecting rod 31 and the filter screen 2 gradually decreases from the end of the connecting rod 31 closest to the filter screen 2 towards the end closest to the protrusion 32. That is, the side of the connecting rod 31 away from the wall of the mounting hole is an inclined plane. The push rod 4 moves in a direction parallel to the axial direction of the mounting hole. Specifically, when the push rod 4 moves into the mounting hole in a direction parallel to the axial direction of the mounting hole, the connecting rod 31 moves towards the slot to push the push rod 4 in order to maintain the connection with the push rod 4. This pushes the protrusion 32 into the slot to fix the filter screen 2. When the push rod 4 moves out of the mounting hole in a direction parallel to the axial direction of the mounting hole, the connecting rod 31 moves away from the slot to push the push rod 4 in order to maintain the connection with the push rod 4. This causes the protrusion 32 to extend out of the slot, so that the filter screen 2 can be removed from the slot.

[0030] An optional implementation of this embodiment is as follows: Refer to... Figures 1-4 Each slot is provided with multiple locking blocks 3. The multiple locking blocks 3 are distributed around the push rod 4 along the moving direction of the push rod 4. The push rod 4 abuts against the multiple locking blocks 3 to synchronously drive the multiple locking blocks 3 in and out of the slot. The multiple locking blocks 3 in each slot can better restrict the filter screen 2 and have a better fixing effect on the filter screen 2. More preferably, the multiple locking blocks 3 are evenly distributed around the push rod 4 along the moving direction of the push rod 4, so that the multiple locking blocks 3 can be subjected to force more evenly, thereby making it easier to fix the filter screen 2. In this embodiment, there are two locking blocks 3.

[0031] An optional implementation of this embodiment is as follows: Refer to... Figures 1-4 The push rod 4 includes a first rod body 41 and a second rod body 42. The first rod body 41 is slidably mounted on the filter screen 2 and moves along an axial direction parallel to the mounting hole. The locking block 3 is located outside the first rod body 41. When there are multiple locking blocks 3, they are distributed along the axial direction of the first rod body 41 outside the first rod body 41, so that the distance between the multiple locking blocks 3 and the first rod body 41 is equal, thereby facilitating the synchronous movement of the multiple locking blocks 3 and the equal distance they move. One end of the second rod body 42 is mounted on the periphery of the first rod body 41, and the other end is mounted on the locking block 3. The second rod body 42 corresponds to the locking block 3 one-to-one. When the first rod body 41 moves, the second rod body 42 moves with the first rod body 41. Since the distance between the locking block 3 and the first rod body 41 is equal, the length of the second rod body 42 is equal, so that when the first rod body 41 moves, it drives the second rod body 42 to drive the multiple locking blocks 3 to move synchronously.

[0032] An optional implementation of this embodiment is as follows: Refer to... Figure 2 The card block 3 is provided with a guide groove 311. The second rod 42 is slidably installed in the guide groove 311. The second rod 42 slides along the guide groove 311, so that when the second rod 42 moves with the first rod 41, the second rod 42 moves along the guide groove 311. Specifically, the end of the second rod 42 away from the first rod 41 is provided with a slider 5 that moves in the guide groove 311. The slider 5 is always located in the guide groove 311. Optionally, a baffle can be provided at the opening of the guide groove 311. The baffle restricts the slider 5 from moving out of the opening, so that the second rod 42 can be connected to the slider 5 through the opening. Since the connecting rod 31 will rotate relative to the second rod 42 when it moves, the projection of the slider 5 in the direction perpendicular to the extension of the guide groove 311 is circular.

[0033] An optional implementation of this embodiment is as follows: Refer to... Figure 2The filter screen 2 is provided with a sliding groove 21, and the locking block 3 is slidably installed in the sliding groove 21. The sliding groove 21 is annular and coaxial with the locking slot. After the locking block 3 is installed in the mounting hole, the position of the locking block 3 can be moved along the axial direction of the mounting hole, so as to make it easier to adjust the position of the locking block 3 according to the position of the locking slot, making it more convenient to use.

[0034] An optional implementation of this embodiment is as follows: Refer to... Figure 2 The push rod 4 is screwed to the filter screen 2. The push rod 4 rotates, thereby adjusting the position of the push rod 4, which in turn causes the first rod 41 to drive the second rod 42 to move, and the second rod 42 to drive the connecting rod 31 to move. The screw connection can also fix the position of the first rod 41. After the position of the first rod 41 is adjusted, the thread can prevent the first rod 41 from continuing to move along the axial direction of the mounting hole, thereby better fixing the locking block 3.

[0035] An optional implementation of this embodiment is as follows: Refer to... Figure 2 The slot is ring-shaped and fits the slot with the card block 3. The card block 3 is installed in the slot to prevent the filter screen 2 from moving axially. That is, the card block 3 can be engaged in the slot at any position, which makes it easier to install the card block 3 in the mounting hole and make it easier to engage the card block 3 in the slot.

[0036] In summary, when using this exhaust gas treatment device, the filter screen 2 is installed on the exhaust pipe 1. After the exhaust gas passes through the filter screen 2, impurities in the exhaust gas are removed. When installing the filter screen 2, the locking block 3 is first installed in the mounting hole. Then, the push rod 4 is moved. When the first rod 41 moves, the second rod 42 moves along with the first rod 41, thus synchronously driving the second rod 42 to move multiple locking blocks 3, causing the protrusion 32 to engage in the locking groove, thereby fixing the filter screen 2 to the exhaust pipe 1. When it is necessary to remove the filter screen 2, the push rod 4 moves, pushing the connecting rod 31 away from the locking groove, causing the protrusion 32 to extend out of the locking groove, thus facilitating the removal of the filter screen 2 from the locking groove. The locking block 3 can then be moved out along the axial direction of the mounting hole. Therefore, this exhaust gas treatment device facilitates the installation or removal of the filter screen 2 from the exhaust pipe 1 by pushing the locking block 3 in and out of the locking groove via the push rod 4. No special tools are required for installing or removing the filter screen 2, making it convenient to use.

[0037] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit this application. For those skilled in the art, this application can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
